@Madronaxyz Yes it's multi-faceted, complicated. And perspective matters, 5 or 10X more acreage burned a century ago in the USA than in recent decades. There's a reason hype media (only sort many ever experience) starts the clock around 1984, that was the coolest time of last 100 yrs and the lowest burn acreage.
The highest temps ever recorded were in the 1930's, the Dust Bowl wasn't just bad policy and farming practices. Coincidentally the coldest time in the last 10k yrs was the 1880's when record keeping began.
Warmer climate means more water vapor, more precipitation and of course water vapor dwarfs all other greenhouse gasses combined. CO2 is a bit player in climate, not trivial but not remotely THE driver, naturally it greatly enhances greening of Earth, crop yields and so on.
It also adds a little security from the ultimate catastrophe--too low CO2 to support plant life which has nearly happened a number of times in last few million yrs.
CO2 is correlated to climate very closely but it often lags temperature which makes sense when realizing 40X more of it dissolved in the oceans than in the atmosphere, warmer water holds less.
Climate models don't work, you can't run them backwards to predict, say the Medieval Warm Period, which was 1.5C warmer than today, nor the "Little Ice Age" we are arguably still recovering from. Both of those episodes must be dodged or data modified to fabricate the infamous "hockey stick" farce.
